TITLE: GCN CIRCULAR NUMBER: 43368 SUBJECT: EP260110a: KAIT optical upper limit DATE: 26/01/11 06:29:36 GMT FROM: Weikang Zheng at UC Berkeley <weikang@berkeley.edu> WeiKang Zheng (UCB), Xuhui Han (NAOC), Pinpin Zhang (NAOC) and Alexei V. Filippenko (UCB) report on behalf of the KAIT GRB team: The 0.76-m Katzman Automatic Imaging Telescope (KAIT), located at Lick Observatory, observed the field of EP260110a (Zhang et al., GCN 43363; 43367) starting at 12:19, Jan 10 UT, about 21 minutes after the burst. A set of 20s, 40s and 60s clear (roughly R) filter images were obtained. In our coadd image, we did not detect any new source within the EP-WXT error circle (Zhang et al., GCN 43367) down to a limiting mag of 21.0 mag (Vega) at a mid-time of 1.0 hours after the burst. Our result is consistent with the upper limit reported by other groups (Perez-Garcia et al., GCN 43364; Kang et al., GCN 43365; Antier et al., GCN43366).
